It will work but and a BIG BUT, you will effectively reduce the output of the radio by mismatching the impedance of the output circuit with the speakers. In other words you will need more output power to drive the speakers then you would use if you match the radio with the speakers. This will over time have a detrimental effect on the radio. I don’t suggest you do it. :'(

Yes , i know Larry , the bazooka (4x50w) can handle this 2 or 4 ohms , but i hesitate whether the amp should be more powerful for the infinities and saw the hawg-wired amp(2x75w) would only run with 4ohms-speaker . It seems to me that the bazooka is not strong enough to bring a clear music at high volume , the speakers should be ok .
Could i transforme these 2ohms infinities into 4ohms infinities ?

with your 2 speaker setup you would be 2x100. the only issue now is the HK radio, it distorts before anything else. yesterday , while riding, I set my Ipod EQ to flat, then had my bass on the radio set to 4bars and same with treble, turned the ipod volume 3 clicks down from wide open. I then adjusted the main volume to 3 bars over half.
No distortionm clear sound, rockin at 90mph. now I got get the comm flashed to I can run my lower fairing speakers

Yes , it is getting better , i tested :
 I read about the hogtunes that they do maintenance in the midrange , the same at the infinities means just reducing the bass and the highs to minimum , really good sound and clear music upto 100mph with just the two in face .  :2vrolijk_21:
(The lowers are great  :2vrolijk_21:)

yes, if the bike didn't come with rear speakers you need to have it flashed by the dealer to turn that function on

Are you sure with the 2x100w when only 2 speakers using?
Damn , i think i have to remove the fairing again and try to adjust the gain a little lower than half( i have it a little more than half) and i want to try the filter at half( have it switched on "full" position now) .
 I guess it will improve the sound at low volume so that i can use more bass and high .
